Executive summary:

The Merck Index, 2006

The density of chlorobenzene at 20 °C is 1.107 g/cm³.

Description of key information

According to literature (The Merck Index, 2006) the density of chlorobenzene at 20 °C is 1.107 g/cm³

Key value for chemical safety assessment

Relative density at 20C:

Additional information

Several literature sources were available and provide consistent density values, ranging between 1,05 and 1,25, for the substance. The Merck Index value, considered as a reliable source and covering most of sources, was chosen as key.

Assuming a density of 0,9998 g/cm3 for water at 4°C, the relative density D20/4 for the test substance is 1,107.
